Home unit for direct draw.

I also hooked up my DBV to a bong and used it when i did not own a VHW. But the VHW is leaps and bounds ahead in terms of taste and even extraction, the glass is way purer tasting than the 7th floor ceramic heating element.

Yes i am biased towards the VHW but not because i own it but because is tastes incredibly more pure compared to other vaporizers and that is a proven fact. Its your final call but if you already own a volcano for group sessions, the VHW for personal use will give you that incredible taste which the volcano nor the lsv will.
